Many aspects of a gymnast's motion can be modeled by representing the gymnast by four segments consisting of arms, torso (including the head), thighs, and lower legs, as in the figure below. Thigh O Arm Leg 60° 60° Torso a b In the figure, (b) shows arrows of lengths r, locating the center of gravity of each segment. Use the data below and the cg coordinate system shown in figure (b) to locate the center of gravity of the gymnast shown in figure (a). Masses for the arms, thighs, and legs include both appendages. (Enter your answers in m, to at least three significant figures.)

Please find the Grashof classification and the Barker classification of the two four-bars: (NOTE: distances are in non-dimensional units. Can use inches or cm) P1) L1=d=4, theta1=0 degrees, L2=a=1.6, theta2=60 degrees, L3=b=5.5, L4=c=4.5 P1) L1=d=2.5, theta1=0 degrees, L2=a=2, theta2=45 degrees, L3=b=1.5, L4=c=1.5 Please also draw the four-bars to estimate the unknown angles theta3 and theta4.
